l am trying to link a page back to another page but the page I want to link to won't appear.
Is this a glitch or something.
Have you confirmed that it exists, and that you haven't accidentally deleted it?
If you have the basic editor, it might not work. If you are in the Advanced Editor, then make sure the page actually exists. If you do all of that, and it still doesn't work, then you should write again on here.
